, Application filed June 17,1918. 7 Serial No. 774,181.

To all whom it may concern:

structures and has been devised in order to 3 provide exceedingly eflicient. apparatus which by suitable adjustment ofits parts can be made toretain a dooror thelike in a desired position for ventilation or. other purposes and also for insuring .th'edoor closing automatically when desired without. banging oroccasioning noise. it For brevity, hereinafter the term door will be held to include windowsygates, and like movable structures which hinge or pivot vertically.

My invention broadly consists of a screw late or the like for attachment to a door frame or other fixture and havin' :means for detachably' and pivotally "xi'ng a curved rod thereto in such a manner that it will automatically adjust itself'to the movement and position of the door. The closing action is produced by arranging a spring to act on a pivoted rod or arm having its free end engaging a vertical member carried by a vertical portion mounted on a bracket and which also carries a frictional gripping member slidably mounted Jon the curved rod. The action of the gripping member is controlled by a screw or the like and can be arranged to move freely over or to firmly grip the said rod as preferred.

In order that the details of construction and action of my invention may bemore readily understood reference will now be.

tory drawings, wherein Figure l is a VIQW 1n .planof the invention. Fig. 2 1s a new in side elevation of is a view in elevation, partly infsection, vof portion of Fig. 2, while Figs. 4: and 5 are views in side and front elevation, respectively, of a bracket forming part of the invention. Fig. 6 illustrates in perspective a further modification of the invention.

The numeral 1 designates ascrew plate having twobosses 2 formed thereon or fitted thereto in an approved way. This plate 1 j plates. made to the accompanying sheet of explana- .Patented Oct. 2o, 1914.

is secured the frame of the doorjat that part which is over the pivot or hinge point thereof. The bosses 2 on the said screw plate 1 provldepivotalsupports for the in wardly turned ends of a curved rod 3 and the'ends. of said rod are prevented frombe coming disengaged from said bosses byone or morepins 1. The curvature of the said rod 3 is perfectly regular and forms an arc having its center in thevertical line or axis on which the door is hinged or pivoted. 1 Ifpreferred, the screw platel can be made in two parts, each part beingarranged to. carry a boss 2 lug orsocket for pivotally supporting the ends of the rod 3 so that it the movement and position of the door.

' The curved rod" 3 adapted to pass througha casing 36 fitted to the projecting arm 7 of a bracket S-aflixed to the door in anapproved way." The said casing 36 surrounds the curved rod 3:,and is preferably lined witharubberized leather 9 or other similar material which-is adapted to be pressed upon the periphery of the rod 3 by the action of a screw 10 of preferred construction. A curved plate 17 is positioned between the end of the screw 10 and the lining 9 to insurethe whole surface of the said lining being forced upon and so provide a willrise and fally to accommodate itself to 1 good frictional'grip of the rod 3 when it is desired to secure the door fixedly in fposition. The said curved plate 17 may extend almost around the lining in which caseit is made of metal that will permit of itspringis removed] j v j i If preferred, a curvedplat 18 similar to 17 can be placed above the lining9 which can be madetin; two corresponding parts mg open when the pressure of the screw 10 and conveniently secured to the curved The adjustingscrew 1O can be formed with a peripheral groove which is: adapted to. engage the point of a screw pin 2O adapted to retain it in an operative position. part of the device shown in Fig. 1. Fig. 3

Amodification of the invention consists in freely through the plate.

Recesses 28 are formed in the top and bottom. of the curved rod 3 and adjacent to each end thereof. "The thickness of metal left between the said recesses 28 is slightly less than the width of the narrow port-ions of the -slots-27 in the platel so that wh en the rods 3 are passed through the plate they may be moved sidewise to be engaged the narrow parts of the slots.

- 1 slots.

To insure the ends of the rods being retained in the slots, pawls 29 can be employed and securedto the plate as shown in the drawings. The saidpawls 29 can be fittedto either side of the-plate and can be given any approved shape' The casing 36, provided with internally disposed gripping members is detachably fitted to avertical portion 37 of the bracket 8.

The means for detachably affixing the casing 36 to the bracket 8 may comprise pawls 88 and studs 39 of preferred construction. The said pawls are pivoted on screws 40 fitted to the sides of the vertical portion of the bracket 8 and the studs 39 are fitted to or formed on the sides of the casing 36.

. -A constant closing pressure may be maintained on the door by means of a pivoted arm 41 and. helical tension spring 12 of approved form. A bearing is provided for the pivoted end of the arm 41 in the lug 43 or the like on the screw plate 1 and its outer and free end is adapted to bear against a jaw 44.

'or grooved roller 45 fitted to the vertical portion 3"? of bracket 8 carried .on the upper edge'of the door. The jaw 44 can be given any approved formation and it can be made integral with or be detachably fitted to the bracket 8; One end of the helical tension spring 4L2 is secured to a stud 46 or the like on that end of the screw plate 1 near which the bracket lies when the door is closed and the opposite end is fitted to the pivoted arm 41 at a point near its pivot end.

i From the foregoing description it will be readily understood that the invention provides for a thoroughand efiicient regulator fo'rdoors and the like which can be operated or controlled easily by a man, woman or child.

I Copies of this patent may be obtained for fln operation the door or other movable structure fitted with the invention can be retainedin any desired position and can be moved onlyby a predetermined amount of force which will be governed by the frictional pressure of the gripping member.

By means of the apparatus a person can a door or other momble structure very slightly open so that intruders may be kept out, or the door may be retained wide open, while the amount of opening and closing movement can be regulated by effecting a suitable adjustment of the parts, as preferred.

WVhat I do claim is 1. The combination with a screw plate for attachment to a door frame, of a curved rod pivotally supported on said plate over the path of the door, a bracket fitted to the door and engaging-said rod, a casing surrounding said rod and detachably secured to the bracket, pieces of gripping material litted within said casing, curved plates and a screw in said casing designed to press said pieces upon the rod, a member fitted to said bracket and disposed to receive and have sliding engagement with the outer end of an arm fitted to the screw plate, and a spring connection between said arm and plate, substantially as described.

2. The combination with a curved rod to be set over the path of the door, of a bracket fitted to and loosely engaging said rod, said bracket being carried by'the door, a casing detachably connected to said bracket by hook-like members, and adjustable gripping devices in said casing.

3. The combination with a curved rod to be set over the path of a door and having fixed pivotal supports to be secured to the door frame, of a bracket fitted to the door and a casing detachably fitted to said bracket and having internally disposed gripping members for engaging said rod, substantially as described.

4. The combination with a plate to be affixed to the door frame, said plate having slots with enlarged ends, of a curved rod having recesses adjacent to its ends and adapted to engage the narrow portions or the slots in the said plate.

5. The combination with a plate to be afiixed to the door frame, said plate having slots adapted to receive the ends of a curved rod and support it over the path of the door, of pawls for retaining the ends of said rod in engagement with the slots.

In witness whereof I have signed this specification in the presence of two witnesses.
